# exponent of a prime

I am newbie in SAGE and here. My apologies for any mistake. This is an easy question.

Is there a command that for an integer $m$ and a prime number $p$ returns the exponent of $p$ in $m$?

If not, I would like if the following definition can be improved.

```
def exponent(p,m):
v=m
sol=0
while v%p==0:
v=v/p
sol=sol+1
return sol
```

Thanks.
